various machines available should be made before definite recom- 

 mendations in favour of anyone are made." The essential point if 

 the kernels are to be exported is that these should not be injured in 

 the husking. 



It remains to be considered whether it would be financially more 

 advantageous to ship the dried kernels or to express the oil here and 

 export this only. If the latter course were to be adopted, there 

 would of course be less danger of losses through fermentation of the 

 husks. On the other hand there would probably be less difficulrv" in 

 marketing the kernels than the oil. 



Agriculturally, it would b^ preferable to retain the cil cake ii 

 the country^ where it could be directly or indirectly returned to the 

 soil. Whether the cake can be used as a cattle food remains to be 

 proved. It might be found to possess deleterious or even poisonous 

 effects on cattle. In any case it could be used as a naanure, con- 

 taining as it does a fair percentage of nitrogen. 



Weight of Seeds from Tapped or Untapped Trees. 



As mentioned above Messrs. Macmillan and Pecch state that 

 they find a large difference between the weight of seed from 

 tapped and untapped trees, the latter ' being considerably 

 heavier. The figures they give are 9.I lbs. against 7.8 ibs. pc;r 1,000 

 seeds, a difference of 1.3 lbs. or i5% per cent, on the weight of se^ds 

 from tapped trees. 



To see whether the differ^n.e were an actual one and if so what 

 would it would amount to h.r . and extensive series of weighings 

 was carried out by Mr. Spring. Trees of the same age in the Ex- 

 periniental Plantation and the Public Gardens, Kuala Lumpur, >.T.ve 

 an excellent opportunity for comparison. The following are the 

 actual results : —
